1 Sniff the line yourself before anything else
A combustible gas detector does what your nose cannot — it reads parts-per-million of methane or propane in air, not just the added odorant. I walked mine slowly along every visible gas line in the utility room, behind the dryer, and under the range. The detector chirped behind the stove connector. That was a $4 flex fitting causing the problem. Do this before you call anyone, because knowing where the leak is saves you the diagnostic fee.
2 Replace the flexible connector behind your range or dryer
Flexible gas connectors are rated for about 20 years, and North Port's high humidity accelerates corrosion on the brass end fittings. If your appliance has not moved since it was installed, that connector has sat in the same bent position for years. The Eastman stainless connector is a direct swap — no special tools, just two adjustable wrenches and fifteen minutes. Shut the valve at the wall, swap it, and check with the detector before you light anything.
3 Pressure-test the whole system with a manometer
A digital manometer lets you isolate sections of your gas line and watch the pressure hold or drop over five minutes — the professional version of what a plumber does before signing off on a job. You hook it to a capped test port or a Schrader valve fitting you add yourself. A line that loses more than 0.5 inches of water column in five minutes has a leak somewhere. This is the only test that finds leaks behind walls and in the attic where your nose and detector cannot reach.
4 Bond your CSST to protect it from lightning
Florida leads the nation in lightning strikes per square mile, and an unbonded CSST line can develop a pinhole arc-burn from a nearby strike — no direct hit required. Bonding clamps connect your CSST to the home's grounding electrode system, which gives the surge a lower-resistance path than your gas pipe. This is a code requirement in Charlotte County and takes about two hours with basic electrical tools. I used the Keeney bonding clamp kit because it fits standard 3/4 inch CSST without any modification.
5 Add an automatic gas shutoff at the meter
A seismic or excess-flow shutoff valve installs at the meter and closes automatically if flow exceeds the normal range — like when a line breaks. In North Port, where a hurricane can shift a slab or snap a line in the crawl space, this is the device that stops a gas fire from starting while you are evacuated and the house is empty. The Seismic Shutoff Valve by GasSAFE is UL-listed and works without electricity, which matters when FPL power is out after a storm. A licensed plumber should install this one — it is a twenty-minute job but requires a meter shut and utility coordination.
6 Mount a natural gas alarm inside the house
Your nose adapts to low-level gas concentrations in as little as a few minutes — that is a documented physiological fact, not a scare tactic. A plug-in gas alarm does not adapt. Mount one within 12 inches of the floor in the utility room and one near the range, because natural gas is lighter than air but propane sinks, and many North Port homes have both depending on when they were built. The Kidde KN-COEG-3 detects both carbon monoxide and combustible gas, which doubles the coverage for one device.
The gas line you cannot see is the one worth spending a Saturday afternoon on.
